Overview

Note:
* This manual is applied to green PCB control board delivered before March 2016.

The original firmware is using the 256000 baud rate while the latest version using 9600. The latest version of baud rate will be more stable and also support more for IOS APP.

The steps of this configuration are as follows:

Step 1: Enable Command Mode of Bluetooth Module

1.There are two pads on the back of Bluetooth module, shown as Figure 1. The Bluetooth module enters the command mode when powered up with pads connected.2.Insert the bluetooth module into the right area of the Dobot Controller after the pads connected, shown as Figure 2. If the blue LED is on and doesn’t twinkle, then the module entered the command mode. If the blue LED twinkles, which hints that the pads’ not connected successfully, please redo procedure (1).
